Depletion of Coral Reefs

The chromatic reefs are accented from a number of causes: overexploitation of resources and commercial seek; insalubrious fishing practices that are destroying the habitat; the increasing coastal population, evaluate to double in the next 50 years; overspill of pollutants, sediments and nutrients from land use; disease outbreaks resulting from poor water flavour; and the removal of coastal mangrove forests.

Water pollution has been determine as one of the major causes of chromatic reef depletion (International, 2005). Oil, gasconade and pesticides kill the chromatic and the marine life living in the system, and tender and animal waste and fertilizer is deposited in the ocean from the rivers which receive this waste. This increases the nitrogen level around the reef, causing an overgrowth of algae, which then smothers the reef by cutting it off from temperateness. aimless trash can in like manner disrupt the supply of sunlight to the reef. Discarded fishing nets often get entangled on reefs and snare hundreds of fish and other marine life.

Pollution comes also from construction sites along the coast, and from mining, logging and farming along coastal rivers. The particles cut off the light needed by the coral polyps for growth. Mangroves and sea grasses which act as natural filters are cosmos cut down to create open beaches for public use. coral is mined for use as bricks and road-fill, and the limestone is used for cement making. touring car r

Most destruction of coral reefs in southeastern United States Asia is due to illegal fishing practices and the use of explosives (Southeast, 2005). Blast fishing kills fish and shatters the coral skeleton. The practice was banned in 1985, moreover still remains a major threat to the coral reefs of Indonesia, since it leaves the reefs unsalvageable. Dynamite used to catch departed fish destroys coral briefs form the inside, divergence no room for regrowth, and leaving no place for fish to reproduce, so actually hurts the fishermen too.

Indonesia and the Philippines command roughly 77 pct of the region's coral reefs, and 98 percent of the Philippine reefs are seriously threatened by human activities. Cyanide fishing is also used in these areas to dragoon the fish but is harmful to the coral and all its inhabitants. seventy percent of the coral reefs in the Philippines have been destroyed, and only five-spot percent are in good condition.

Mangrove forests serve as nurseries for many coral species and help maintain the quality of coastal waters by reducing the amount of sediment runoff, pollutants and bare nutrients from the land reaching the waters (Moore and Best, 2005). Construction of shrimp farms for the mankind markets has led to the destruction of many mangrove forests. Trade has also led to the overfishing and selective removal of key groups from coral reefs such as: groupers and wrasses for recognise food fish trade; dead fish and invertebrates for medicinal products and ornaments (sharks, sea cucumbers, sea stars, molluscs, sea horses); live fish, coral and other species for aquaria; and "live rock" - the calcero
